Kind Code:
A
Abstract:
A mobile unit for treating liquid waste to render it non-polluting and fit for ultimate disposal includes a mixing hopper having an inlet for receiving liquid waste, and an outlet for connection to a conduit extending to a disposal area. The unit also includes a bin for a powdered setting agent for a liquid alkali metal silicate. The bin has an outlet at its bottom and a porous floor spaced above its bottom. Compressed air is delivered to the space beneath the floor to form a fluidized bed of setting agent above the floor. The setting agent is delivered to the mixing hopper in which it is mixed with the liquid waste. After the mixture leaves the hopper, liquid alkali metal silicate from a tank in the mobile unit is delivered to the mixture. The treated waste will set after it has reached the disposal area.
